In order to obtain Friable Embryogenic Callus FEC for protoplast isolation we have evaluated in this research the competance for Friable Embryogenic Callus FEC of four cassava cultivars M61033 Rendre Yalipe and Six-mois in media containing MS supplemented with 8mgl 24-D MS supplemented with 10 mgl BAP and GD supplemented with 12mgl picloram using apical bud AB and immature leaves lobes ILL as explants. In general in the medium GD12mgl picloram the highest efficiencies of FEC ranged from 58 to 87 and the highest score of FEC ranged from 4.2 to 5.4 with explants AB however we have observed with explants ILL the efficiencies of somatic embryos ranged form 41 to 75 and the score ranged from 4.1 to 4.4. The mediums MS28 mgl 24-D have induced with explants AB the efficiencies of FEC ranged from 43 to 57 and the score ranged from 3.1 to 3.8 however with ILL explants the efficiencies of FEC ranged from 39 to 49 and the score ranged from 2.9 to 3.7. The least FEC were observed in the medium MS210 mgl BAP with BA explants however the efficiencies ranged from 6 to 11 and the score ranged from 1.1 to 1.8. Whereas the efficiencies of FEC with ILL explants ranged from 4 to 7 and the score ranged from 0.5 to 0.8. All of four cultivars showed capability of producing FEC although their efficiency varied according to gonotype donors explants and medium taking into acount.
